1. Introduction

The cyrus part is only valid for Cyrus-IMAP 2.1.x and Cyrus-SASL 2.1.x. If you plan to use Cyrus-IMAP 2.0.x
then please consult the deprecated version 1.0.x of this HOWTO.

I strongly recommend that you upgrade to Cyrus Version 2.1.x. If you do so, you will have a better ability to get
valuable support from the user community

1.2. Why I wrote this document

There are different approaches on how to set up different mailsystems. Most documents that are available are
related to Sendmail, procmail, WU-IMAPd and friends. These packages are very good but are unfortunately very
inflexible in their user administration.

For a long time I was testing alternative MTA's like qmail, postfix and exim, in conjunction with IMAP/POP-servers like
Cyrus, vpopmail, Courier IMAP and others.

At the end of the day, from my point of view the couple Postfix/Cyrus seems to be the
most flexible and best performing solution.

All these combinations of software had one thing in common: their was very little documentation available
describing how these packages work together with each other.
To install the software, lot of effort has be spent to get all information needed to get all the
software running.
